JOSEPH P. CENTNER, OF PITTSBURG, PENNSYLVANIA.

CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 296,274, dated April 1,1884.

v Application filed August 24, 1883. (No model.)

To ctZZ whom it may concern.-

Be it known that I, JosErH P. OENTNER, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inRailroad-Oar Brakes;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in railway-car brakes; and theobject is to produce a railway-car brake that is reliable at all times,automatic in its operation, simple in construction, very powerful in itsapplication, and not liable to get out of order.

The invention consists in the construction and arrangement of certainparts of a railwaycar brake, which will be more fully describedhereinafter, reference being had to the accompanying drawings, and theletters of reference marked thereon.

Like letters of reference indicate like parts in the different figuresof the drawings, in which- Figure 1 represents a plan view of my improved railway-car brake. Fig. 2 is a longitudinal section of the same.Fig. 3 is a detail view of the draw-bar.

In the drawings, A represents the frame or body of a car of any ordinaryconstruction, having at each end the bumper B. To the inner end of saidbumpers are attachedthe main draw-bars 0, connected at the central partof the frame to levers D by means of sliding rods (1 d. A cross-piece,a, is secured at each end of the frame, between which and the end of thebumper is arranged aspring, e, on the'bars 0, while another spring, f,is placed between theframe-piece A and a bar, 9, secured to the innerend of the bar 0. The rods 01 slide freely through these bars, 9 withone end, while the opposite ends of said bars are secured to anangle-piece, g, secured. to the bars 9.

Between the levers D is arranged a pivoted lever, E, which is connectedat opposite ends to the outer ends of the levers D by means of the linksh, while the extreme ends of said levers D are guided in slotted ways27, secured to the frame-pieces A. The central lever is pivoted at k,and is guided on each side in slotted ways 1. Toward the ends of thelevers are attached the rods m, which pass through angle-pieces a,secured to the central parts, A, 5 5

of the frame A, and between the piece A and the angle-piece a is placeda spring, 0, oventhe rods m. These springs serve to draw the levers Dalways back to their normal position.

- To the extreme outer ends of the central lever, E, are attached thechains or rods p,which connect with the brake-blocks or brake-bars.Another rod, 11, extends to and is connected with the ordinary handbrake-shaft q, for operating the brakes by hand. 6 5,

The brakes may be operated by a steam or compressed-air cylinder placedon the locomotive or tender, so as to be operated by the engineer fromhis cab, or can be manipulated by the ordinary hand brake-wheel on eachcar. The springs on the bars C also tend to force the levers back totheir normal position, and take-the brake-blocks out of contact with thewheels, and thus render the brake automatic.

The rods d serve to steady the action of the 7 levers D, and preferablyone is placed above and the other below thecentral lever, E.

It will be readily seen that by this arrangement a very powerful,simple, and reliable brake is obtained, which is not liable to get outoforder, and can be easily applied to cars now in use, and is automatic inits operation.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is- 85 1. In railway-car brakes, the combination ofthe draw-bars C, provided with springs e and f, with a central lever, E,connected by links h to the levers D, having attached to them the rods(1 (1, arranged substantially as specifled.

2. The combination of the draw-bars G, provided with springs c andf,with a central lever, E, connected by links h to the levers D, havingattached to them the rods d d and spring- 5 rods m, arranged as shown,and for the purpose set forth.

The combination of the draw-bar 0, provided with springs c and f, acentral lever, E, connected by links it to the levers D, having I00attached to them the rods d d and spring-rods irframe, all constructedand arranged substan- IO m, with the rods and chains 19 and p, foropertialiy as described and shown.
